JAMES E. BROOKS, OF GLEN RIDGE, NEW JERSEY.

FIREPROOF ROOF.

SPECIFICATION forming part of Letters Patent No. 667,292, dated February5, 1961.

Application filed May 11, 1900- To ctZZ whom it may concern:

Beit known that I, JAMES E. BROOKS, a citizen of the United States,and aresident of Glen Ridge, in the county of Essex and State of New Jersey,have invented a certain new and useful Fireproof Roof, of which thefollowing is a specification.

The present invention relates to the construction of roofs, and has forone object the prevention of sagging and mayhap the falling offireprooflinings. Another end attained is the provision of a dead-airspace between a metallic roof or weather-course and a lining offireproof material, as one having asbestos as its base. Other objectswill appear hereinafter.

To these ends the invention consists of features of construction andcombinations of devices hereinafter described, and more particularlypointed out in the appended claims.

The invention is illustrated in the accompanying drawings, forming partof this specification, in which- Figure 1 is an end elevation of a roofin which the invention is embodied. Fig. 2 is a detail view, partly insection. Fig. 3 is a view from underneath of one form of the invention.Fig. 4 is a detail view, partly in section. Fig. 5 is a plan view ofanother form of the invention. Fig. 6 is a cross-section of a stiffenedlining. Fig. 7 is a section of the form shown in Fig. 5. Figs. 8 and 9are detail views of a connection between rafters and purlins.

The same part will be referred to by the same reference character.

In the drawings, 1 indicates walls; 2, rafters; 3, purlins; 4, anoutside course, skin, or coveringshown as corrugated-metal roofingresting on the purlins; 5, squares or the like of non-combustiblelining, as one having asbestos or the like as a base.

In Figs. 2, 3, and 4 the lining 5 is shown as being secured directly toflanges of channelbars or purlins by means of bolts and nuts 6 andcorrugated-metal strips 7, the last named acting as stiffeners for thelining, which otherwise would sag, and thus open the seams, and perhapseven fall out. The stiffeners 7 are placed at the edges of the squares 5and also at intermediate points and are continu- Serial No. 16,255. (Nomodel.)

ous from one purlin to another in this form of the invention.

In Figs. 5 and 6 the strips7 are of a length such that they pass betweenadjacent purlins and are secured to the upper sides of the squares 5 byrivets or other suitable fasteners, and two opposite edges of thesquares rest on the washers 8 on the bolts and nuts 6, by which thelining is suspended at intervals from the purlins. V The strips 7prevent sagging of the lining in this form also.

The rafters and purlins are preferably separated by a space sufficientfor the insert-ion of the lining between them, as by connecting themtogether by means of angle-supports 9, which are bolted or riveted torafter and pu rlin, as shown in Figs. 8 'and 9. Certain of the seams oredges of the lining-squares then rest on the rafters and the remaindercome between them.

While Iihave shown strips of corrugated metal for the stiffeners, I donot limit myself thereto, since other forms of stiffener-strips maybeused withoutdeparting from the scope of my invention and claims.

Having thus fully described my invention,

what I claim as new, and desire to secure by LettersPatent of the UnitedStates, is

' 1. A roof construction comprising an outer covering of metal, spacedsupports therefor, and an inner lining of non-combustible material atthe under side of the supports, with metallic stiffeners for saidlining, and means for securing the parts together, in combination,substantially as described.

2. A roof construction comprising an outer metallic covering, spacedsupports therefor, an inner lining of non-combustible material, metallicstilfeners for the lining, and means for suspending said lining andstiffeners from the under side of said supports, in combination,substantially as described.

3. A roof construction comprising an outer metallic covering, purlins,rafters, supporting-angles connecting and spacing apart the rafters andpurlins, an inner lining of noncombustible material passing between saidrafters and purlins, and metallic stiffeners attached to said liningbetween purlins, in combination, substantially as described.

4. A roof construction comprising an outer metallic covering, spacedsupports therefor, lins at a distance from the rafters to provide aninner lining of non-combustible material spaces for the edges of liningmaterial, subat the under side of said supports, metallic stantially asdescribed. stifieners at the under side of the lining and A Signed atNew York, in the county of New 5 extendingfrom supportto support, andmeans York and State of New York, this 9th day of [5 for attaching thelining and stiffeners to the May, A.
